Caution

Regarding RoHS compliance: The products are RoHS non-compliant only when alteration BMC is selected. The products are RoHS-compliant when BMC is not selected. As some parts used in the alteration are RoHS non-compliant, the RoHS notation on this page has been changed to non-compliant. "Non-compliant" is also indicated in the certificate due to information on the left.
Please note that the swaged flange options, NFC, RFC, and LFC, are not reflected in the CAD data.

Standard Tooth Profile

Tooth groove dimensions slightly vary according to the number of teeth. (Pitch: 5.0mm)

[ ! ] Surface treatment may not be applied to the shaft bores.
[!] Two types of bushings are available: standard type (ST bushings) and short type (SH bushings).
[ ! ] Unless otherwise specified except for teeth and F dimensions, the dimension tolerance conforms to JIS B 0405 Class m.
